Abstract: A pixel structure and an organic light emitting display are disclosed. The pixel structure includes a plurality of pixels which includes a plurality of sub-pixels. At least one pixel forms a pixel unit, and longitudinally adjacent pixel units are arranged in a vertical mirror image, and/or laterally adjacent pixel units are arranged in a horizontal mirror image. The present disclosure may increase the area of mask opening during evaporation, reduce the difficulty of mask production process, and reduce the evaporation process difficulty by a reasonable pixel arrangement structure and allowing sub-pixels of adjacent pixels to share one mask opening to evaporate. It does not need to preset a gap during evaporating the sub-pixels of adjacent pixels of the mask, thereby a real high PPI is achieved while keeping the opening ratio. In addition, the present disclosure can further increase the strength of the mask.

Abstract: A pixel circuit and a method therefor, and an organic light-emitting display. The pixel circuit initializes an anode of an organic light-emitting diode (OLED) by means of a first thin-film transistor, a second thin-film transistor and a seventh thin-film transistor, and initializes a gate and a drain of a sixth thin-film transistor serving as a driving element by means of the first thin-film transistor, a third thin-film transistor and the seventh thin-film transistor so that the service life of the OLED and the service life of the sixth thin-film transistor are prolonged. The current output by the sixth thin-film transistor serving as a driving element is irrelevant to the threshold voltage of the sixth thin-film transistor and the impedance of the power wiring, and thus uneven brightness caused by deviation of the threshold voltage of the thin-film transistor and different impedances of the power wiring can be avoided.
